Diagram view: bug if "source" and "destination" are inverted

[Francois Degrave]

Hi!

When trying to create a diagram view for one of my own objects, I always got a strange error, the same that the one I reported in https://bugs.launchpad.net/openobject-server/+bug/932830 . However, the latter bug is for diagrams with cyclic transitions, and this bug arose even when there was NO cycle in my transitions. I finally just inverted "source" and "destination" in the arrow element in the view, and now it works OK (but the arrows are not in the correct direction).

Of course, this bug should not arise when the direction of the arrow is inverted, since the definition is symmetric.

You can easily check this bug by inverting the "source" and "destination" fields in "workflow_view.xml":

          <arrow object="workflow.transition" destination="act_from" source="act_to" label="['signal','condition']">
            <field name="act_from"/>
            <field name="act_to"/>
            <field name="signal"/>
          </arrow>

Cheers!
